Appreciate a joke publicly from ruffian about a month in the summer at hotel that's garish (5,3,4)
I believe the answer is:
laugh out loud
'appreciate a joke publicly' is the definition.
I know nothing about this answer so I can't judge whether this works.
'ruffian about a month in the summer at hotel that's garish' is the wordplay.
'ruffian' becomes 'lout' (I've seen this before).
'about' means one lot of letters goes inside another.
'month in the summer at hotel' becomes 'ugh' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'that's garish' becomes 'loud' ('loud' can be a synonym of 'garish').
'a'+'ugh'='augh'
'lout' placed around 'augh' is 'laughout'.
'laughout'+'loud'='LAUGH OUT LOUD'
'from' is the link.
Can you help me to learn more?
(Another definition for laugh out loud that I've seen is " Extremely funny".)
